HI83305 Multiparameter Photometer with Digital pH Electrode Input for Boilers and Cooling Towers The HI83305 benchtop photometer measures 18 dierent key water quality parameters using 32 dierent methods. This photometer features an innovative optical system that use an LED, a narrow band interference ¡lter, a focusing lens, and both a silicon photodetector for absorbance measurement and a reference detector to maintain a consistent light source to ensure accurate and repeatable photometric readings every time. Specially designed for use with boilers and cooling towers, the HI83305 is a comprehensive way to maintain precise water conditions within these systems. Problems such as corrosion, deposition, and microbial growth can occur if these key parameters, such as oxygen scavengers and silica, aren’t maintained. Oxygen scavengers are added to remove residual dissolved oxygen in boiler feed water that can cause corrosion in a steam generating plant. It is important that levels of oxygen scavengers be routinely checked to prevent corrosion and ensure that equipment is working e¤ciently. Boiler water maintenance is necessary to prevent or control deposit formation as seen with silica. Silica contamination can reduce system e¤ciency and increase maintenance of equipment due to scaling. • Advanced optical system · Innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette • Backlit 128 x 64 Pixel Graphic LCD Display · Backlit graphic display allows for easy viewing in low light conditions · The 128 x 64 Pixel LCD allows for a simplified user interface with virtual keys and on-screen help to guide the user through use of the meter • Built-in Reaction Timer for Photometric Measurements · The measurement is taken after the countdown timer expires. · Countdown timer ensures that all readings are taken at the appropriate reaction intervals regardless of user for better consistency in measurements • Absorbance mode · Hanna's exclusive CAL Check™ cuvettes for validation of light source and detector · Allows for the user to plot concentration versus absorbance for a specific wavelength for use with user supplied chemistry or for teaching principles of photometry • Units of Measure · Appropriate unit of measure along with chemical form is displayed along with reading • Result Conversion · Automatically convert readings to other chemical forms with the touch of a button • Cuvette Cover · Aids in preventing stray light from affecting measurements • Digital pH Electrode Input · Measure pH and temperature with a single probe · Good Laboratory Practice (GLP) to track calibration information including date, time, buffers used, offset and slope for traceability · pH CAL Check™ alerts user to potential problems during the calibration process · Space saving having a pH meter and photometer built into one meter • Battery Status Indicator · Indicates the amount of battery life left • Data Logging · Up to 1000 photometric and pH readings can be stored by simply pressing the dedicated LOG button.
